ESP8266 gateway using RFM95 LoRa

Hi.
I want to use an ESP8266 as gateway, but not with NRF24, but with RFM95, respectively Ra-02 (same SX1278 chip).
The ESP8266 gateway example code has already an option to use an RFM95 as radio.
Anything else besides this that I have to configure?

How do I connect the RFM95 to the ESP8266? Are the connections exactly the same as for RFM69, or is there something different?
